Abstract

Abstract Dendrite-shaped iron nanowires with 50–200 nm in diameter and 10–20 μm in length were prepared by the CVD method from Fe(CO) 5 as a starting source. Ethanol was cracked on the surface of the resultant iron nanowires to form the Fe 3C/carbon nanocomposites, in which nanosized carbon beads covered the surface of Fe 3C. Resin compact of the resultant Fe 3C/carbon nanocomposites had excellent electromagnetic wave absorption ability in the range of 0.9–9.0 GHz, and such available absorption range more enhanced compared to that observed on the resin compact prepared from the original iron nanowires by the hybridization of magnetic (Fe 3C) and dielectric (carbon) materials.
